Forward J/ψ production at the Fermilab Tevatron
(American Physical Soc, 1999-12-01)
The DØ Collaboration has recently reported the measurement of J/ψ production at low angles. We show here that the inclusion of color octet contributions in the framework of the soft color model is able to reproduce this ...
EXPECTATION OF FORWARD-BACKWARD RAPIDITY CORRELATIONS IN p plus p COLLISIONS AT THE LHC ENERGIES
(World Scientific Publ Co Pte LtdSingaporeSingapura, 2012)
Shining light on polarizable dark particles
(Springer, 2017-04-14)
We investigate the possibilities of searching for a self-conjugate polarizable particle in the self-interactions of light. We first observe that polarizability can arise either from the exchange of mediator states or as a ...
Forward-angle incoherent photoproduction of pseudoscalar mesons off nuclei
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
The mechanism of forward angle incoherent photoproduction of pseudoscalar mesons off nuclei is revisited via the time-dependent multicollisional Monte Carlo (MCMC) intranuclear cascade model. Our results-combined with ...
Forward scattering approximation and bosonization in integer quantum Hall systems

Parametric decays of a linearly polarized electromagnetic wave in an electron-positron plasma
(1997)
We study the parametric decays of a large amplitude, linearly polarized electromagnetic wave in an electron-positron plasma. We include harmonic generation, the ponderomotive force, and weakly relativistic effects. It is ...
Influence of a dynamical gluon mass in the pp and (p)over-bar-p forward scattering
(American Physical Soc, 2005-08-01)
We compute the tree level cross section for gluon-gluon elastic scattering taking into account a dynamical gluon mass, and show that this mass scale is a natural regulator for this subprocess cross section. Using an eikonal ...
A new observable in extensive air showers
(Elsevier Science, 2016-12)
We find that the ratio rμe of the muon to the electromagnetic component of an extended air shower at the ground level provides an indirect measure of the depth Xmax of the shower maximum. This result, obtained with the ...
gamma p and gamma gamma scattering from (p)over-bar-p, pp forward amplitudes in a QCD eikonal model with a dynamical gluon mass
(American Physical Soc, 2006-04-01)
We examine the gamma p photoproduction and the hadronic gamma gamma total cross sections by means of a QCD eikonal model with a dynamical infrared mass scale. In this model, where the dynamical gluon mass is the natural ...
Perdas qualitativas na colheita mecanizada de sementes de soja
(2013-03-01)
The study aimed to assess the physical and physiological characteristics of soybean seeds collected in grain tank and the outlet of the discharge tube of the harvester, depending on the year and the forward speed of the ...
